About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Plastic Pipe and Pipe Fittings for Water

Standard-Wall Plastic Pipe for Water

Connect this pipe to standard-wall plastic pipe fittings for a variety of residential and commercial low-pressure plumbing and water supply applications.

Clear-View Standard-Wall Plastic Pipe for Water

See inside your line with this clear pipe, which works in a variety of residential and commercial low-pressure plumbing and water supply applications.

Thick-Wall Plastic Pipe for Water

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Clear-View Thick-Wall Plastic Pipe for Water

See what’s flowing through your line with this clear pipe. Since it’s Schedule 80, this pipe has thicker, stronger walls than standard-wall pipe, so you can use it for heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

CPVC Pipe for Hot Water

Connect to CPVC pipe fittings for use in high-temperature plumbing and water supply applications up to 170° or 200° F.

UV-Resistant Standard-Wall PVC Pipe for Water

This Schedule 40 pipe is typically used in low-pressure residential and commercial plumbing and water supply applications. It can handle pressures up to 300 psi. Suitable for outdoor environments, it contains an additive that protects against the damaging effects of ultraviolet light. Connect to UV-resistant PVC pipe fittings.

UV-Resistant Thick-Wall PVC Pipe for Water

With thicker, stronger walls than standard-wall pipe, this Schedule 80 pipe can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Use for pressures up to 550 psi. Suitable for outdoor environments, it contains an additive that protects against the damaging effects of ultraviolet light. Connect to UV-resistant PVC pipe fittings.

Plastic Pipe and Pipe Fittings for Chemicals

High-Temperature PTFE Pipe
Nipples and Pipe for Chemicals

This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It is commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

UV-Resistant Polypropylene Pipe for Chemicals

This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand acids, solvents, and other harsh substances.

High-Purity PVDF Pipe for Corrosive Chemicals

Made of PVDF that’s finished to a 12 Ra smoothness, this pipe handles some of the harshest chemicals without leaching contaminants into your line.

Fiberglass Pipe for Corrosive Chemicals

With excellent corrosion resistance, this pipe can handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. Layers of fiberglass give this pipe better strength and durability than any of our other pipe for chemicals.

High-Purity Polypropylene
Pipe for Corrosive Chemicals

The inside of this pipe won’t leach contaminants into your line or accumulate particles—it’s polished to an ultra-smooth 12 Ra finish, which also makes it easy to clean. Made of polypropylene, it resists organic solvents, acids, and alkalis better than CPVC pipe.

Easy-Access CPVC Pipe for Chemicals

Also known as Victaulic pipe, this pipe has grooved ends that connect to fittings and flanges with a clamp, so you can access your line for routine maintenance. It is CPVC, which has excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances.

Flame-Retardant PVDF Pipe
Nipples and Pipe for Chemicals

Pipe meets UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. It is made of PVDF, which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances.

Drain, Waste, and Vent ABS Pipe for Chemicals

This pipe is an economical choice for gravity-flow chemical waste systems. Pipe is ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Gravity-Flow Polypropylene Pipe
for Corrosive Chemical Waste

Made of polypropylene, this gravity-flow pipe stands up to tough organic solvents, such as acetone, that would dissolve CPVC pipe. You can also use it for lines with highly corrosive acids, such as hydrochloric acid, and alkalies.

Gravity-Flow CPVC Pipe for
Corrosive Chemical Waste

Use this pipe in gravity-flow applications that involve highly-corrosive chemicals–it is NSF certified for use in corrosive waste systems. Pipe is made of CPVC, which has better chemical resistance than ABS plastic to stand up to acids and other harsh substances.

Plastic Pipe and Pipe Fittings for Drain, Waste, and Vent

Underground Snap-Lock Polyethylene
Pipe for Drain, Waste, and Vent

Pipe has a snap-together design that allows you to quickly connect to fittings with no cement required. It is typically used in gravity-flow drainage applications.

Underground PVC Pipe for Drain, Waste, and Vent

This pipe has thinner walls than Schedule 40 pipe, so it’s lighter in weight and has more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines.

Aluminum Quick-Connect Pipe for Compressed Air

Build a compressed air system in half the time it would take to build a copper or steel system.
